Valence electrons-The electrons in the outer energy shell.
Chemical bonding- The force of attraction that holds atoms together.
Hyroscopic-absorbs water easily
Covalent bonds
can be shown with electron (or lewis) dot diagram.
compounds made by sharing valence electrons
compounds are called molecules only in covalent bonds
simplest forms are called diatomic molecules
Metallic bonds
electrons are shared throughout the compound.
properties of these compounds include conductivity, malleability, and ductility
only happen between metals Ionic bonds
formed between a metal and nonmetal
compounds made by atoms losing or gaining electrons, making ions that attract eachother
The negative ion changes its name to end in "ide"
There is one problem with the Chloride compounds. They are hygroscopic materials. This means that they absorb water easily, deminishing the color effect.
